I just managed but it is somewhat complicated this time around (compared to in Mint 13) if you want all the Gnome Shell/Gnome 3 goodies. Merely installing the gnome-shell package doesn't give you Online Accounts integration, nor does it give you the full System Settings menu (gnome-control-center).

Pretty hard to retrace my steps now but I think I first installed "gnome-shell" and "gnome-shell-extensions", then pinned Ubuntu's repos higher than Mint's in the the etc/apt/preferences file, then installed "gnome-session", then added the Gnome 3 PPA and pinned it highest of all, then installed "gnome", then reinstalled "gnome-control-center". Now I have something close to vanilla Gnome 3, + Nemo and the Cinnamon session. Online Accounts works and the System Settings menu is there in full.

As mentioned above you'll have to use gdm instead of mdm, but that also makes more sense in a Gnome Shell environment anyway, as gdm is tightly integrated with Gnome Shell and mdm isn't. For instance lock screen only works with gdm.

If anyone knows of an easier way then please share as this would probably be a good topic for a guide/tutorial

And by the bye, Gnome Shell is very fast and responsive on top of Mint 14, certainly more so than on top of 12.10.

Thank you for this thread. That’s all I can say. You most definitely have made this forum into something special. You clearly know what you are doing, you’ve covered so many bases. Thanks!

Does anyone know if there's any trouble using the new GDM3 with Cinnamon (on main Nadia)? I tried it on my laptop just installing 'gnome-shell' and it seems to be OK. But I want to be more sure before I put it on the 'family-PC'.

I did not install gnome-session, because it seems to draw in full unity with it. After just installing Gnome-shell I got the new GDM, but no Gnome-shell as option in session. That's okay because I just wanted GDM. IMHO the new GDM fits better with Cinnamon. There's no black screen after login and the 'faces'from user accounts are shown (they don't in MDM).

But mayne somebody did the same and had some trouble/breakage?

GDM 3.6/the new lock screen is currently fairly broken in quantal, when you resume from suspend you just get a black screen with a mouse cursor. The bug is fixed in GDM 3.6.2, but of course quantal still has 3.6.1 :/.

That does not give you the full gnome-shell experience - e.g. you don't have online accounts integration, which is essential to gnome-shell, and your settings menu is maimed. It's only uncomplicated if you don't mind running a botched gnome-shell session.

Yes, sources tweaking and a few installations/uninstallations. I really wish there were a proper guide for this (or that I had down carefully what I did) as gnome-shell on top of Mint 14 (Cinnamon) is quite awesome. Maybe some remastersys wizards will do gnome-shell Mint 14

I did all this and it worked for me except that I found out that I could not find an 'Appearance' option in 'Settings' to allow for a change of desktop background. If I Right Clicked on desktop and selected 'Change Desktop Background' it just took me to 'Settings' with no 'Appearance' option.

I finally solved it by opening Synaptic Package Manager and used it to install gnome-panel-control . I then rebooted to find the 'Appearance' option in 'Settings' (and Right Click Change Desktop) as normal.
